CASEMENT-WINDOW.

Specification of Letters Patent.

Patented June a, 1918.

Application filed November 9, 1917. Serial No. 201,028.

To all whom it may concern:

Be it known that I, IRVING H. EnLIorr, a citizen of the United States, residingat New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Casement- Windows, of which the following is a specification.

The invention is a casement window, comprising a fixed quadrangular frame to be seated in the masonry of the window opening, and a swinging quadrangular sash frame which enters said fixed frame, and when closed abuts against the front edge of a flange turned on the rear edge of said fixed frame. There is a clearance around said sash frame and between the same and said fixed frame. On the front edge of the sash frame is formed a bead which enters a correspondingly formed groove in the front side of the fixed frame, in which groove is an elastic packing strip, agamst which said bead bears. There is no contact between the sash frame and the fixed frame other than at the joint between bead and groove, except, of course, when the sash ism closed position, and this omt is always tightly packed.

The sash frame is swung on hinges, the knuckles of which enter recesses in the bead on one side of said frame, the said knuckles in cross section registering with said bead.

The invention consists in the construction hereinafter set forth.

In the accompanying drawings- Figure 1 is a front elevation of my casement.

Fig. 2 is an enlarged section on the line at, a: of Fig. 1.

Fig. 3 is an enlarged section on the line y, y of Fig. 1.

Fig. 4 is an enlarged horizontal section through one hinge on the line 2, z of Fig. 6, showing said hinge in closed position.

Fig. 5 is a similar section, showing the hinge in open position. a

Fig. 6 is an elevation of the hinge and of a portion of the sash frame.

Similar numbers of reference indicate like parts.

1 is the quadrangular metal fixed window transverse member preferably formed integrally in a single piece. Extending around 2 which enters a suitable groove 3 in the masonry, wherein said frame is seated. The rear face of groove 3 is wider than the front face, and the rear face of flange 2 is of corresponding width so as to seat itself against said rear groove face.

On frame 2 is formed a shoulder 4, into which the angle of the brick work enters. On the rear edges of the upper horizontal member and the two vertical side members of frame 2 is a flange 5 which is turned twice at right angles, so that its front edges, at 6, form the seat or abutment for the sash frame when the sash is in closed position.

The horizontal members of frame 1 have on their outer faces downwardly turned flanges 7, 8, Fig. 3. The upper surface of the upper horizontal member is flat in front of flange 2. The width of flange 2 on its front side is less than its width on its rear side, in order to break joints between the frame 1 and the surrounding brickwork on opposite sides of said flange, and so impede the entrance of drafts or moisture around thenxed frame.

On the frontface of frame 1 is formed a groove 9 of arc-shaped cross section, and in the metal of said frame is embedded a strip 10 of elastic packing which protrudes slightly into said groove 9.

The metal sash frame 11 is quadrangular in shape, and preferably integrally formed of a single piece. Its dimensions are to be such as to permit it to enter frame 1 with an all around clearance 12. On the inner periphery of frame 11 is a flange 13, against which the glass pane 14: bears, said pane be ing secured in place by glazing strips 15 which are secured by screws 16 on the rear edge of sash frame 11. Packing strips 17 may be introduced on opposite sides of the pane 14. The glazing strips 15 rest against the front edges 6 of flange 5 of fixed frame 1, when the sash is in closed position, Fig. 4.

The sash frame 11 is outwardly flared, and its edge is molded to form a bead 18 which fits in the groove 9 of frame 1, and bears against the elastic packing strip 10 in said groove.

The sash frame 11 is supported in the fixed frame 1 by means of hinges-two, similarly constructed, being here shown. One leaf 19 of each hinge is secured by screws 20 to the front side of frame 1. The other leaf 21 is secured by screws 22 to the sash 5. The knuckle of each hinge side, where the glazing strips abut against the outer edges 6 of flange5. The bead 18 thus entering groove 9 and bearing on strip 10 forms a close joint with frame 1, While the clearance around the sash frame 11 permits said frame to be freely swung to open and close the same.

I claim:

1. A casement window, comprising a fixed frame and a swinging sash frame entering said fixed frame, the said sash frame having at its outer edge a bead, and the said fixed frame having in its outer face a groove receiving said bead, there being a clearance in rear of said head surrounding said sash frame and between said sash frame and said fixed frame.

2. A casement window, as in claim 1, and an elastic strip seated in said fixed frame and protruding from the inner periphery of said groove and bearing on said bead.

3. A casement window, as in claim 1, and

registers with aaeaaaa a hinge for supporting said windoubbfie leaf of said hinge being secured to said fixed frame, the other leaf being secured to said sash frame, and the knuckle of said hinge being received in a recess in said bead and registering in cross section with said bead.

4. A casement window, comprising a fixed frame and a swinging sash frame entering said fixed frame, the said fixed frame having on the rear edges of its side members and of a transverse member an outwardly turned flange forming an abutment for the rear side of said sash frame when in closed position.

5. A casement window, comprising a fixed.

frame and a swinging sash frame, the said fixed frame having at its rear edge a flange forming an abutment for said swinging frame whenin closed position, and on its front side a groove, and the said sash frame having at its outer edge a bead adapted to fit in said groove, there being a clearance around said sash frame and between said sash frame and said fixed frame, the said clearance being bounded by said fixed frame flange and the joint between said bead and said groove.

In testimony whereof I have affixed my signature in presence of two witnesses.
